Discover the ultimate protection for high-voltage relays with our premium ceramic relay housing – engineered from high-purity alumina ceramic for unmatched performance and reliability in demanding applications.
Crafted with superior white porcelain-like structure, this advanced ceramic shell delivers exceptional electrical insulation, extreme heat resistance, and outstanding corrosion resistance. Using state-of-the-art vacuum brazing and metallization techniques, it creates a hermetically sealed arc-extinguishing chamber filled with inert gases (like hydrogen mixtures) to effectively suppress arcs, ensuring safe, reliable switching even under intense high-voltage and high-current conditions.
Why choose our ceramic relay housing? Standout advantages include:
- Unrivaled strength and durability: Superior tensile and bending strength to resist vibrations and mechanical stresses – built to last in harsh environments.
- Top-tier insulation and voltage endurance: Exceptional breakdown voltage rating, perfectly suited for new energy vehicle HVDC relays and beyond.
- Extreme temperature tolerance: Operates flawlessly in environments exceeding 175°C – far outperforming traditional plastic or epoxy alternatives.
- Perfect airtight sealing: Blocks dust, moisture, and contaminants, dramatically extending relay lifespan and maintaining peak stability.
Trusted worldwide in electric vehicle battery management systems, charging stations, and power electronics, our ceramic relay housing is the essential core component empowering the future of clean energy and high-power innovation. Elevate your system’s safety and efficiency today!
